2017考研英语拓展阅读:元素周期表将添四位新成员
Four new elements have been added to the periodictable, finally completing
the table's seventh row andrendering science textbooks around the worldinstantly
out of date.
据悉,元素周期表将要新添四名新成员,第七行元素将得以完整,而这将使全世界的化学教材瞬间成为过去时。
The elements, discovered by scientists in Japan,Russia and America, are the
first to be added to thetable since 2011, when elements 114 and 116
wereadded.
本次由日本、俄罗斯和美国科学家发现的元素是既2011年114和116号元素加入周期表以来,首批加入的新元素。
The four were verified on 30 December by the US-based International Union
of Pure andApplied Chemistry, the global organisation that governs chemical
nomenclature, terminologyand measurement.
这四个元素由位于美国的国际纯粹与应用化学联合会于12月30日证实,这个世界性的组织负责着化学界的命名法、术语和测量。
IUPAC announced that a Russian-American team of scientists at the Joint
Institute for NuclearResearch in Dubna and Lawrence Livermore National
Laboratory in California had producedsufficient evidence to claim the discovery
of elements 115, 117 and 118.
国际纯粹与应用化学联合会宣称,一支由俄罗斯杜布纳联合原子核研究所与美国加利福尼亚劳伦斯利弗莫尔国家实验室的美俄科学家组成的队伍,已掌握了充分的证据来证实115号、117号和118号元素的存在。
The body awarded credit for the discovery of element 113, which had also
been claimed by theRussians and Americans, to a team of scientists from the
Riken institute in Japan.
俄罗斯和美国的科学家们还宣布发现了113号元素,联合会把这一荣誉授予了来自日本理化研究所的科学团队。
Kosuke Morita, who was leading the research at Riken, said his team now
planned to “look tothe unchartered territory of element 119.”
理化研究所的Kosuke Morita是这次研究的领导者,他说他们的队伍正计划“探索119号元素尚未开垦的领域。”
Ryoji Noyori, former Riken president and Nobel laureate in chemistry said:
“To scientists, this isof greater value than an Olympic gold medal”.
研究所前主席和诺贝尔化学奖获得者野依良治表示:“对于科学家来说,这比获得奥运金牌的价值还要重大。”
The elements, which currently bear placeholder names, will be officially
named by the teams thatdiscovered them in the coming months. Element 113 will be
the first element to be named inAsia.
现在这几个元素还是无名氏,接下来的几个月,它们的发现者队伍将会正式为其命名,113号元素也将成为第一个在亚洲命名的元素。
New elements can be named after a mythological concept, a mineral, a place
or country, aproperty or a scientist.
新元素可以依据某一虚拟概念、矿物或者按发现地点、发现者的国家或者由元素的特性或某个科学家来命名。
The four new elements, all of which are man-made, were discovered by
slamming lighter ?nucleiinto each other and tracking the following decay of the
radioactive superheavy elements.
这四个新元素都是人造的,是由火花与原子核相互撞击并且循着放射性超重元素衰变的轨迹而发现的。 |
